While working on first revision to Boost.Test I thought about very same
issue in regards to fatal/system errors during testing: How to help
programmer to locate where in test case problem occurred? I was about to
implement automatic "checkpointing" when I realized that in fact it is
already in place in existent implementation: Just set log  level to "all"
and last pass/fail message will give you all information you need.

So I do not believe any extension is required in this matter.

--report_level=[confirm,short,detailed,no]
environment variable: BOOST_TEST_REPORT_LEVEL

Be aware that after setting environment variable in windows you may need
to restart GUI, so it will pick up new value.
